There is a big difference: a furnace is a simpler system, which burns a fuel releasing heat, that can be converted into other forms of energy, with a limited conversion efficiency; on top of that, a furnace releases particulate matter in the atmosphere and the residues require disposal. SyngaSmart gasification system allows to generate a flammable gas that can be used for generating thermal power, but also electric power (CHP configuration), without releasing PM and with a valuable byproduct (biochar)
